Michael Egli ff448e3485 Fix some UB cases. Closes #546 
There are two cases of UB that are fixed in this commit.

1. In ethercatmain.c, there are two left shifts of 31:

    (1 << 31)

Because 1 is a signed int by default, the result cannot be represented
in an int. The fix is to explicitly make the 1 unsigned.

2. In ethercatconfig.c, for slaves that have no inputs, the code would
   apply an offset to a NULL pointer. The fix is to test that the slave
   has inputs available before applying the offset.

Both cases were found by clang with the help of UBSan.
